TL;DR: In this review, the negative effects and challenges of applying biochar for the remediation of HM-contaminated soils are thoroughly summarized and discussed, including the changeable characteristics of biochar, biochar over-application, toxic substances inBiochar, activation of some HMs in soils by bio char, nonspecific adsorption, and the negative influences of bio char on soil microorganisms and plants.

TL;DR: BCM was a porous-like flake material and that modification increased its specific surface area and surface functional groups and reduced the mobility of Cd and Cu in soil and transformed them to more stable fractions.

TL;DR: Wang et al. as discussed by the authors collected 43 pairs of soil and grape samples from vineyards in the suburbs of Kaifeng city (wastewater-irrigated area in Henan Province, China) to assess the heavy metal (Pb, Cd, Cu, Zn and Ni) pollution level in soil, heavy metal accumulation in different grape tissues and the potential health risk via consumption of grapes.

TL;DR: It is indicated that MPTS/nano-silica has long-term stabilization effects on Cd in agricultural soil and is a potential amendment for the remediation of Cd-contaminated agricultural soils.

TL;DR: In this article , surface sediment samples were collected from the Arctic Ocean and Bering Sea to determine the content of metal(loid)s (As, Cu, Cd, Ni, Pb, Zn and Cr).
